samba ldap pdc

Hello all.
I have a problem, when I want to log into a domain.
I have no problems to join computer, but when I try to connect a user to
this domain, I got an error : user does not exist.
But the most important thing, in the message on the samba server logs :

rpc_server/srv_netlog.c:api_rpcTNP
api_net_sam_logon:Failed to marshall NET_R_SAM_LOGON
api_rpcTNP:api_netlog_rpc:NET_SAMLOGON failed.

What the meaning of these messages ????
Please thank you.

Alain.
